Sarah Palin isn’t vice president. And she probably won’t ever be president. Heck – she’s not even a governor anymore.

But the Alaskan pol has achieved one measure of fame – someone’s written an opera about her.

“Say It Ain’t So, Joe,” a presentation by Guerilla Opera, opens Saturday at Boston Conservatory’s Zack Box Theater. The work is composer Curtis Hughes’ musical take on America’s favorite moose-hunting winker, you betcha. It focuses on that contentious – and sometimes comical – debate from October 2008 between Palin and Joe Biden, though the show also includes cameos from Hillary Clinton, Gwen Ifill, Diane Sawyer and, of course, the right-wing’s favorite Everyman, Joe the Plumber.
